Apple used MPW internally for Mac development by ≈1986, as others have noted. MPW was a Unix-like environment. However, the MPW toolchain was much slower to compile and link.
In any case, by the 486 era, a serious developer would have wanted to run a 68030-based Mac at minimum, which would have been a similar experience to this video, but much faster and often on a larger screen.
- jjuran 5y agoMPW was certainly Unix-inspired, but its multitasking was seriously deficient compared to a real Unix. Its runtime environment couldn't run more than one binary executable ("tool") at a time — not even using `system()` — so MPW's Make couldn't actually run anything, but merely printed out the commands. Only the user and MPW Shell scripts could execute other programs.
